Tip.
Unless about at least 30,000 turnout can be guaranteed, it comes too close on the heels of a nearly 100,000 turn out by illegal alien supporters.
The media, hopelessly pro-illegal and leftist, will show the distinction and will not stop driving the point home.
Therefore, I suggest this event be held inside, in an auditorium of some sort. Fill it to the rafters and then invite the media.
This is just a strategic comment, not pouring water on the fire.
We could hurt our cause (think in the minds of Joe Sixpack watching these) if the turnout is pitiful in a comparative sense.
